compatability

I have a polaris 90cc engine with CVT and wanted to know if other engine brands can be bolted to it , specifically will it work with pred 212cc

Will this driver belt pulley be a good part to put on my Hilltopper mini where it is missing? MAX TORQUE TCDRS34 TORQUE CONVERTER DRIVER UNIT 3/4" SHAFT REPLACES COMET 219559 It looks like a Comet but is either a CHICOM knock off or other make.

Does anyone know offhand if an HMSK80 flywheel will fit my lighted HM80 engine, and if so do I need to use the coil and stator off the HMSK? Thanks
